Re: rownum

Others have already come up with answers for Oracle8, but for 7.3+ (maybe earlier) you can still use an in-line view to achieve the result. Although you may not be able to "order by" within it in Oracle 7, I'm pretty sure you can still "group by" on a primary key value, which automatically always sorts (i.e. orders by) as a result.
